[physics]: model choices, cutoffs and energy overrides.

Fields

potential: PotentialChoice

Screening function. Default "zbl".

screening_length: Option<LengthChoice>

Screening length. Default: the length conventionally paired with the screening function (Screening::default_length); filled in on resolution and echoed.

stopping: StoppingChoice

Electronic stopping. Default "lindhard-scharff".

free_path: FreePathChoice

Free-path convention. Default "constant".

min_cm_angle_deg: Option<f64>

Smallest centre-of-mass deflection treated as a collision, degrees; required with free_path = "energy-dependent", rejected otherwise.

weak_collisions: u8

Weak collisions per collision step, 0..=3 (crate::ion::bca::BcaConfig::weak_collisions); constant free path only. Default 0.

primary_cutoff_ev: f64

The primary stops below this energy, eV. Required.

recoil_cutoff_ev: f64

Recoils stop below this energy, eV. Required. Keep it below the smallest E_s when sputtering matters.

follow_recoils: bool

Follow displaced atoms as full cascades. Default true.

primary_surface_binding_ev: f64

Planar surface barrier for the beam species, eV. Default 0.

energies: BTreeMap<String, EnergyOverride>

E_d/E_b/E_s overrides by element symbol, applied to that element in every layer after the material’s own values (so they win).

tuning: String

Opt-in phenomenological calibration: "none" (default) or the name of a versioned factor set (TuningSet). Not a published model choice. See TuningSet for what it scales and where it applies.
